DRAFT-RIGGING YOKE.

Specification of Letters latent.

Patented Oct. 9, 191".

Application filed April 14, 1916, Serial No. 91,237. Renewed August 27, 1917. Serial No. 188,495.

To all whom it may concern Be it known that I, STACY l3. HAsEL'rINE, a citizen of United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Draft-Rigging Yokes, of which. the following is a full, clear, concise and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in draft rigging yokes.

' The object of the invention is to provide a draft rigging yoke which may be detachably connected with all standard types of draw-bars Whether the latter are provided with coupler key slots or not.

- Another object of the invention is to pro vide a detachable dravubar and yoke connection so arranged that all the. parts are readily accessible at the front end of the yoke and wherein the draw-bar. may be reinflved without disturbing the gear.

In the drawing forming a part of this specification, Figure 1 is a part longitudinal section and a part side elevation of a draw bar and yoke showing my improvements in connection therewith, a friction gear being indicated diagrammatically by dotted lines,

Fig. 2 is a broken horizontal sectional view taken substantially on the line 22 of Fig. 1. Fig. 3 is a vertical sectional view taken substantially on the line 33 of Fig. 1. Fig$-4 is a front end elevation of the yoke. Fif. 5 is a bottom plan of the yoke. And Fig. 6 is a perspective view of the locking block employed.

In said drawing, 10 denotes a. standard draw-bar having an upper shoulder 11, lower shoulder 12, and 13 indicates a frietion gear of a well known type. The yoke A, as shown, comprises an upper arm 14, lower arm 15, rear connecting piece 16, and a hollow rectangular hood or head at its front end, said ,hood having an upper wall 17, side walls 18-18, and bottom wall 19. The upper wall 17 is provided with a depending, transversely extending shoulder or gib 20 which cooperates with the draw-bar shoulder 11, said gib 20 being curved on its rear face as indicated at 21 to thereby er mit radial movement of the draw-bar. he lower wall 19 of the hood, which is downwardly offset from the arm 15, is provided on its upper face with two longitudinally extending channel shaped grooves or recesses 22-22 on opposite sides thereof, said grooves 22-22 thereby forming a central shoulder 23 between the grooves which terminates at the line indicated at 24, (see Figs. 1 and 2). To detachably engage the draw-bar with the yoke, I provide a locking block B, said block B being substantially a. flat member having an upwardly extending shoulder 25 at its front end which extends transversely of the block. B and is arranged to engage the lower shoulder 12 of the drawbar.- Said shoulder 25 is also convexly curved on its inner face as indicated at 26 to permit said radial movement of the drawbar. At its rear end, the block B is provided with a pair of spaced, depending lugs or projections 27-27 which fit and slide within said recesses 22-22, said lugs 27 being spaced apart suiiioiently to slide past said shoulder or rib 28. The block B is also preferably tapered rearwardly so as to snugly fit against the side walls 18.-18 which are also tapered for the purpose of permitting the radial movement of the draw'bar. To retain the block B in position, I provide a rectangular plate 28 which is insertiblc and removable through vertically extending recess 29 in the bottom wall of the hood, said recess being so located that the block 28 when in position will bear against the end 24 of said rib 23. The retaining plate 28 may be held in position by any suitable means such as the bolt 30 which passes throu h perforations in the plate 28 and in depending ears {ii-31 formed on the lower face of the hood. A slot 32 is provided at the rear of the hood in the bottom wall thereof to permit the insertion of a suitable tool to facilitate removal of the locking block.

The parts are shown in assembled relation in Fig. 1 and in order to disconnect the draw-bar, the bolt 30 is first removed, then -the plate 28 is withdrawn downwardly, after whereupon the draw-bar may be withdrawn 110 forwardly through the open end of the hood. it is believed that the method of assembling the parts will be apparent from the foregoing description.

I. elaim 1' 14 A yoke having a hooded forward rod provided with means for engaging the up per shoulder oi a thaw-bar, and removalilr devices for cooperating with the lower shoulder of the drznv-har, said devices in eluding a shouldered locking hloelr rninov able from the front end of the hood, and a retaining plate insertiblo through a slot in the bottom of the hood, said block liming shoulders on its underside at the roar of said plate to engage the latter when the parts are orm'ativoly assembled.

2. A yoke having a hollow, rectangular head the bottom Wall thereof having a lon flitut inully (:iit"lltilil{ slot on the wow are thereof. a locking: block having; an n wardlv extending whonhh-r adapted to -ngage the lower ehoulder of a dran'd'iar. suni l'lork linking aiao a d pending lop; .-;ii luhlr within said slob and a retaining plate in sertible through a slot in. said bottom wall adapted to engage said block and hold it in position.

3. A yoke having a hood at its forward end within which a draw-bar butt is adapted to be received, the bottom wall of said hood having a pair of longitudinally extending slots on the inner face thereof, a locking block removable through the open front end of said hood, said hloek having depending lugs movable within said slots, and a taining plate for holding said block in operative position. t

*l. A vast yoke for railway draft riggings having' a hollow hood at its forward end within whieh is adapted to be received the butt of a drzuvhar, the upper wall of said hood having an integral transveraely extending shoulde and the bottom wall of said hood having a longitudinally extending rooxe in the inner tare thereof, a shouldered locking hloeh instertiliile from the front ol said hood, said block having a depending lug slidalv le within said slot, and a transversely arranged retaining plate insertihle through an opening in the hottonuwall of mid hood said plate being located forwardly of said top; when the parts a re assembled and How-hr pxrirntine said hloeli l'roni pullingout :r. A yolze for draft. riggings having a rrrtan gular hollo brad at its: front end,

said. luau! being prori'lrtl with integral Hl 'dil? for engaging do; upper portion. of a ri'an' air hunt and {itt-i'tiilllik devices for the toner portion of a draw-hair managing: butt, said devices including a block having a shoulder on its upper face and depending lugs on its lower fare, and a retaining plate insrrtihle through an opening, in the bottom wall of the hooth said. lugs engaging the rear "face of said plate when the parts are in assembled position.

In witness that I claim the foregoing I have hereunto subscribed my name this 15th day of Main. 1916.
